答案

1、be surrounded by 是被包围的意思,这里不是过去式的表示,是说小镇被树木包围着,表被动.
2、这里的on sundays是泛指星期天的意思,是统称.假如你用了every了,就不能接复数,every sunday可以,表示每个星期天.
3、其实这里用rubbish与litter都可以,不过litter也可以做动词用.
4、这里的主语是what i saw(这里是指看到的东西),谓语动词是made,所以不需要接to,如果加了to就是累赘.
5、among the rubbish这里的意思是,在这堆垃圾里面（暗指签名是里面其中一个）,而假如你写成“in the rubbish",则是对这垃圾做了个独立的统称,这样与原话的意思有出入的,因为把你的话翻译过来就是：我发现了一个签名,这签名是写在垃圾上的.这样的话,和原话“我在垃圾堆中发现一个签名写着……”是不一样的.
